Welcome to the R1a and all Subclades Haplogroup Project. To participate, you are not required to order a test kit or take another test, just click the Join button. *** Note that the results page has a "Page Size" feature. Change the default from 500 to 5000 to see all results! *** Important: Please change your Administrator Access Level to Limited or Full Access in order to assist with kit management and to better facilitate project research. The default level (Group only) makes it impossible to work with!
